Basalt stones are mostly carbonate products,and the stone structure itself does not contain metallic elements,so generally speaking,the internal structure of basalt stone will not rust or turn yellow.Basalt stones and granite have essential differences,with the same external factors but different internal factors.
The reason for the yellow surface of basalt stones can generally be:
1.Pollution from colored substances,such as juice,beverages,tea leaves,pigments,dyes,etc.
2.Alkaline pollution:such as grass ropes,cardboard boxes,sawdust,etc.
3.Apply protective agent before the stone is completely dried,or after baking and sun exposure.Water is wrapped in stones and reacts with calcium oxide in basalt stones to form calcification.
4.Basalt stones are in a damp or semi damp state,with surface waxing,polishing,or crystal hardening.They react with water seals or crystal hardening to slightly neutralize basalt rocks.
5.The ore body separates from the ore body and naturally turns yellow.
Light colored basalt stones can turn yellow with a little carelessness;However,this is not scary.No need to deal with it,except for the five types of yellowing that cannot be alleviated at once,but before installation,it is possible to avoid or focus on regional characteristic paving.The other 1-4 types of yellow are acquired,and it is not difficult to relieve them with targeted medicine.
The rust yellow of basalt stones is caused by the oxidation of metal substances on the surface of the stone due to moisture or acidic corrosion,leading to pollution.For such lesions,basalt stone reagents and methods should not be used to remove yellow color,and specialized rust removers should be used to remove metal oxides.Marble rust remover may have some therapeutic effect,but the surface of the stone is corroded and damaged.
That's all for this issue.Basalt stones that turn yellow or rusty yellow should be treated differently,and different situations should be treated differently.
